Cracks in Shinko tire

I just noticed that my one season old Shinko 705 rear tire has cracks at the bases of all the lugs. This is a radial tire purchased in Canada.

I have been advised by the Canadian importer that the warranty is 180 days.

Has anyone had issues with cracking on the 705 radials?
Were you able to get any warranty service from Shinko?

Most any tire with a block type tread, and a deep tread, will develop some "cracks" at the base of the block. It is due to stretching back and forth. Some Shinkos have been known to have the block delaminate from the carcass. Which is probably another problem not related to this. But pictures would help.

The three most negative review of these tire at revzilla complain of failures.

Shinko 705 Dual Sport Tires - RevZilla

When buying a tire at this price range, I think you give up a little in consistency in manufacturing. Most people have really good luck with them but others... well, they don't.

For me, I am willing to spend the extra bucks to push the odds up that I will get a good product when it comes to MC tires.

The most expensive tires out there are not any more reliable, don't be fooled by price either way.

That's 3 negative reviews out of 103 reviews. Also, those reviews include both bias ply and radial versions. The older bias ply ones were know to have some separation/delam issues on the heavy bikes. I have not heard of any of these issues on the radials.

Yeah I can find a rash of failures with Michelin Pilot Roads of various flavors.

Anywho to the OP, for the 705 and 804/805 a little bit of this is normal. The deep tread patterns and tall blocks result in a lot of "stretching" as stated above. I've seen TKCs do similar.

A picture or two would help.

Without pictures we have no idea if what the OP wrote has anything to do with the 705 failures that involved delamination.

Look at a set of TKC 80's, or Michelin Wilds, and see what it looks like where the blocks attach to the carcass. And they ain't cheap tires...........

To be clear, I am not putting down the Shinko tire. Many people like them a lot and have very good luck with them for many safe miles.

That said, any tire (no matter the price) that shows failures of this type will not be high on my list of choices. I like to hustle my bike and need to have a level of comfort regarding the small patches of rubber that keep me from crashing. Just one man's opinion.

Well, I'm about to put 2500 miles on my new set over the next few days, so I'll have to keep an eye on it.

Seriously, these tires seem to be pretty polarizing; 90 percent of the reviews seem pretty positive, and then the other ten percent spin them as substandard handling, too fragile, noisy, etc. I've only had them on for a couple hundred miles, but so far, I like them.
